Most of the mega concrete projects are carried out through prestressed concrete units.
The only precaution taken is for their transportation.
This is a special technique in which the bars or the tendons used in the concrete is stressed before the actual service load application.
During the mixing and the placing of the concrete, these tensioned bars placed firmly and held from each end of the structural unit.
The most commonly used heavy weight aggregates is Barytes.
These types of aggregates are most commonly used in the construction of atomic power plants and for similar projects.
The use of lightweight aggregates in concrete design will give us lightweight aggregates.
Aggregates are the important element that contributes to the density of the concrete.The normal strength concrete has an initial setting time of 30 to 90 minutes that is dependent on the cement properties and the weather conditions of the construction site.The plain concrete will have no reinforcement in it.Different types of concrete are produced based on the constituent material, mix design, the method of construction, area of application, form of hydration reaction.Details of these various types of concrete, their properties and applications are discussed.The reinforced cement concrete is defined as the concrete to which reinforcement is introduced to bear the tensile strength.
